Lungela ukungena ezweni elijabulisayo lama-algorithms athandwa kakhulu okuhlunga!

Ama-algorithms okuhlunga ayi-10 adume kakhulu

1. I-Bubble Sort Algorithm

I-algorithm yokuhlunga amabhamuza ingenye yezindlela ezilula nezilula ukuziqonda. Igama layo livela endleleni izakhi "ezibhamuza" ngayo ohlwini njengoba zihlelwa. Inqubo ihilela ukuqhathanisa amabhamuza ezinto eziseduze, futhi uma zilandelana ngendlela engafanele, zishintshe. Le nqubo iphindaphindwa kuze kube yilapho uhlu lonke luhlelwa.

I-algorithm yokuhlunga ibhamuza kulula ukuyisebenzisa, kodwa ayisebenzi kahle kumasethi amakhulu edatha. Isikhathi sayo esiyinkimbinkimbi ngu-O(n^2), okusho ukuthi isikhathi sayo sokwenza sikhuphuka ngokuphindwe kane ngosayizi wohlu. Nakuba ingafaneleki kumasethi amakhulu edatha, ingaba usizo ezimeni lapho uhlu seluvele luhlungwe khona noma lapho usebenza namasethi amancane edatha.

2. I-Algorithm Yokuhlunga Kokufaka

I-algorithm yokuhlunga yokufakwa ingenye i-algorithm elula kodwa esebenzayo. Isebenza ngokuhlukanisa uhlu lube yisigaba esi-odiwe kanye nesigaba esinga-odwe. Ekuphindaphindweni ngakunye, i-elementi ithathwa esigabeni esingahlungiwe futhi ifakwe endaweni efanele ngaphakathi kwesigaba esihlungiwe. Le nqubo iyaphindwa kuze kube yilapho ingxenye engahlungiwe ingenalutho futhi lonke uhlu luhlungwa.

I-algorithm yohlobo lokufaka lusebenza kahle kakhulu kune-algorithm yokuhlunga ibhamuza, nesikhathi esiyinkimbinkimbi se-O(n^2). Nokho, ukusebenza kwayo kungase kuthinteke kabi ngamasethi edatha amakhulu, angcolile. Noma kunjalo, kuyinketho esebenzayo yamasethi edatha amancane noma uhlu oseluvele luhlungiwe.

3. Ukukhetha Hlunga I-algorithm

I-algorithm yokukhetha ilula kodwa iyasebenza. Ekuphindaphindweni ngakunye, ithola into encane ohlwini bese iyishintshanisa nento yokuqala engahlungiwe. I-algorithm ibe isithuthela endaweni engahlungiwe elandelayo futhi iphinda inqubo kuze kube yilapho lonke uhlu luhlungwa.

Nakuba i-algorithm yohlobo lokukhetha inobunzima besikhathi buka-O(n^2), isebenza kahle kakhulu kunokuhlelwa kwebhamuza nokufaka ama-algorithms okuhlunga ezimweni eziningi. Nokho, ukusebenza kwayo kwehlisa isithunzi ngamasethi amakhulu edatha. Naphezu kwemikhawulo yayo, ihlala iyinketho esebenzayo yamasethi wedatha encane noma izimo lapho kudingeka khona i-algorithm elula ukuyisebenzisa.

4. I-Quick Sort Algorithm

I -algorithm ye-QuickSort ingenye yama-algorithms okuhlunga asebenza kahle kakhulu futhi adumile. Isebenzisa indlela yokuhlukanisa nokunqoba ukuhlunga uhlu. Okokuqala, ikhetha isici se-pivot bese ihlukanisa uhlu lube ama-subset amabili: elilodwa elinezinto ezincane kune-pivot kanti elinye elinezinto ezinkulu. Bese, liphinda inqubo efanayo kuma-subset amabili kuze kube yilapho uhlu lonke luhlelwa.

I-algorithm ye-quicksort inesilinganiso sesikhathi esiyinkimbinkimbi se-O(n log n), okuyenza ibe ukukhetha okuhle kakhulu kumasethi amakhulu edatha. Nokho, ukusebenza kwayo kungase kwehliselwe ku-O(n^2) esimweni esibi kakhulu uma i-pivot ikhethwe ngokungafanele. Ngaphandle kwalokhu, i-algorithm ye-quicksort isasetshenziswa kabanzi ngenxa yokusebenza kahle kwayo ezimweni eziningi.

5. Hlanganisa Ukuhlunga I-algorithm

I-algorithm yokuhlunga ukuhlanganisa, eyaziwa nangokuthi i-MergeSort , isebenzisa indlela yokuphindaphinda ukuhlukanisa uhlu lube ama-subset amancane bese iwahlanganisa ngokulandelana. Okokuqala, ihlukanisa uhlu phakathi kuze kube yilapho ithola ama-subset ento eyodwa. Bese, ihlanganisa ama-subset ngokulandelana, iqhathanisa futhi ihlanganisa izinto ku-iteration ngayinye.

I-algorithm yokuhlunga yokuhlanganisa inesikhathi esiyinkimbinkimbi se-O(n log n), okwenza isebenze kahle kumasethi amakhulu edatha. Ngokungafani ne-algorithm yokuhlunga okusheshayo, i-algorithm yokuhlunga yokuhlanganisa inokusebenza okufanayo futhi ayithintwa izimo ezingezinhle. Nokho, kudinga isikhala esengeziwe ukuze ugcine amasethi angaphansi ngesikhathi sokuhlanganisa.

6. I-Algorithm Yokuhlela Igobolondo

I-algorithm ye-Shell Sort, eyaziwa nangokuthi i-ShellSort, iwukuthuthukiswa kwe-algorithm yokufaka. Esikhundleni sokuhambisa i-elementi endaweni yayo efanele ngokushesha, i-algorithm ye-ShellSort isebenzisa ukulandelana kwezikhala noma ukweqa ukuze iqhathanise futhi ihambise izinto ezikude ngokuhlobene. Njengoba i-algorithm iqhubeka, izikhala ziyancishiswa kuze kube yilapho ekugcineni kwenziwa uhlobo oluphelele.

I-algorithm yokuhlunga ye-Shell iphumelela kakhulu kune-algorithm yokufakwa ezimweni eziningi, kodwa ayisebenzi kahle njenge-QuickSort noma i-MergeSort algorithms. Isikhathi saso esiyinkimbinkimbi sincike ekulandeleni kwegebe elisetshenzisiwe, kodwa esimweni esibi kakhulu ngu-O(n^2). Noma kunjalo, kungaba inketho ethokozisayo yamasethi edatha anosayizi omaphakathi.

7. I-Algorithm Yokuhlunga Kwenqwaba

I-algorithm yokuhlunga inqwaba, eyaziwa nangokuthi i-HeapSort, isebenzisa ukwakheka kwedatha okubizwa ngokuthi inqwaba ukuze kuhlungwe uhlu. Inqwaba isihlahla esiphelele kanambambili lapho inodi yomzali ngayinye inkulu noma ilingana nezingane zayo. I-algorithm yakha inqwaba ohlwini olungahlelekile bese ikhipha ngokulandelayo isici esiphezulu (impande yenqwaba) futhi iyibeke endaweni yayo efanele.

I-algorithm yokuhlunga inqwaba inesikhathi esiyinkimbinkimbi se-O(n log n) futhi isebenza kahle kakhulu kumasethi amakhulu edatha. Nokho, ukuqaliswa kwayo kungase kube nzima kakhulu ngenxa yokusetshenziswa kwesakhiwo sedatha yenqwaba. Ngaphandle kwalokhu, i-HeapSort isalokhu iyinketho edumile yezimo ezithile.

8. Ukubala Hlunga I-algorithm

I-algorithm yohlobo lokubala iyinketho ekhethekile yokuhlunga ama-elementi aphelele ebangeni elithile. Esikhundleni sokuqhathanisa nezinto ezihambayo, i-algorithm ibala inani lokuvela kwe-elementi ngayinye bese yakha kabusha uhlu ngokulandelana.

I-algorithm yohlobo lokubala inobunzima besikhathi buka-O(n + k), lapho u-n eyinombolo yezakhi futhi u-k kuwububanzi bamanani angaba khona. Isebenza kahle ngokwedlulele ngokwesikhathi sokusebenza, kodwa idinga indawo eyengeziwe yokugcina amaza ama-elementi. Ngenxa yemvelo yayo ekhethekile, i-algorithm yohlobo lokubala ifaneleka kuphela kumasethi edatha athile.

9. I-Radix Hlunga I-algorithm

I -algorithm yokuhlunga i-radix ingenye i-algorithm ekhethekile yokuhlunga izinombolo eziphelele. Esikhundleni sokuqhathanisa nokuhambisa izinto, i-algorithm ihlela izinombolo ngokusekelwe kumadijithi ezindaweni ezahlukene. Iqala ngokuhlunga izinombolo ezingabalulekile kakhulu bese iqhubekela phambili kwebaluleke kakhulu.

I-algorithm yokuhlunga ye-radix inesikhathi esiyinkimbinkimbi sika-O(n * k), lapho u-n eyinombolo yezakhi futhi u-k eyinombolo yamadijithi enombolweni enkulu kakhulu. Nakuba ingase isebenze kahle ngokwesikhathi sokusebenza, ukuqaliswa kwayo kungase kube nzima kakhulu ngenxa yokuguqulwa kwamadijithi. I-algorithm yohlobo lwe-radix isetshenziswa kakhulu ukuhlunga izinombolo ezinhlelweni ezithile.

10. I-algorithm yokuhlunga ibhakede

I-algorithm yokuhlunga amabhakede, eyaziwa nangokuthi i-BucketSort , ifaneleka ekuhleleni izinto ezisatshalaliswa ngokulinganayo ebangeni elithile. Ihlukanisa uhlu lube yinani elinqunyiwe lamabhakede, isabalalise izinto emabhakedeni ngokwenani lazo, bese ihlela ibhakede ngalinye ngokwehlukana. Ekugcineni, ihlanganisa wonke amabhakede ohlwini olulodwa oluhleliwe.

I-algorithm yokuhlunga ibhakede inesikhathi esiyinkimbinkimbi sika-O(n + k), lapho u-n eyinombolo yezakhi futhi u-k eyinombolo yamabhakede. Isebenza kahle ngokwesikhathi sokusebenza, kodwa idinga indawo eyengeziwe yokugcina amabhakede. I-algorithm yokuhlunga ibhakede iwusizo ikakhulukazi uma ama-elementi asatshalaliswa ngokulinganayo ebangeni futhi aziwa kusengaphambili.
